More than ever, Israel is isolated from world opinion and the squishy entity known as “the international community.” The Israeli government keeps condemning the Iran nuclear deal, by any rational standard a positive step away from the threat of catastrophic war.

In the short run, the belligerent responses from Prime Minister Benjamin Netanyahu are bound to play badly in most of the U.S. media. But Netanyahu and the forces he represents have only begun to fight. They want war on Iran, and they are determined to exercise their political muscle that has long extended through most of the Washington establishment.

While it’s unlikely that such muscle can undo the initial six-month nuclear deal reached with Iran last weekend, efforts are already underway to damage and destroy the negotiations down the road. On Capitol Hill the attacks are most intense from Republicans, and some leading Democrats have also sniped at the agreement reached in Geneva.

A widespread fear is that some political precedent might be set, undercutting “pro-Israel” leverage over U.S. government decisions. Such dread is inherent in the negative reactions from Netanyahu (“a historic mistake”), GOP lawmakers like House Intelligence Committee chair Mike Rogers (“a permission slip to continue enrichment”) and Senator Saxby Chambliss (“we’ve let them out of the trap”), and Democratic lawmakers like Senate Foreign Relations Committee chair Robert Menendez (“this agreement did not proportionately reduce Iran’s nuclear program”) and Senator Charles Schumer (“it does not seem proportional”).

Netanyahu and many other Israelis — as well as the powerhouse U.S. lobbying group AIPAC and many with similar outlooks in U.S. media and politics — fear that Israel’s capacity to hold sway over Washington policymakers has begun to slip away. “Our job is to be the ones to warn,” Israel’s powerful finance minister, Yair Lapid, told Israeli Army Radio on Sunday. “We need to make the Americans to listen to us like they have listened in the past.”

This winter and spring, the Israeli government and its allies are sure to strafe U.S. media and political realms with intense barrages of messaging. “Israel will supplement its public and private diplomacy with other tools,” the New York Times reported Monday from Jerusalem. “Several officials and analysts here said Israel would unleash its intelligence industry to highlight anticipated violations of the interim agreement.” Translation: Israel will do everything it can to undermine the next stage of negotiations and prevent a peaceful resolution of the dispute over Iran’s nuclear program.

Looking ahead, as a practical political matter, can the U.S. government implement a major policy shift in the Middle East without at least grudging acceptance from the Israeli government? Such questions go to the core of the Israeli occupation now in its 47th year.

Israel keeps building illegal Jewish settlements in the West Bank; suppression of the basic human rights of Palestinian people continues every day on a large scale in the West Bank and Gaza. There is no reason to expect otherwise unless Israel’s main political, military and economic patron, the United States, puts its foot down and refuses to backstop those reprehensible policies. They can end only when the “special relationship” between the USA and Israel becomes less special, in keeping with a single standard for human rights and against military aggression.

Such talk is abhorrent to those who are steeped in the notion that the United States must serve as a reliable enabler of Israel’s policies. But in every way that those policies are wrong, the U.S. government should stop enabling them.

The longstanding obstacles to such a halt stand a bit less tall today, but they remain huge. No less than before, as William Faulkner said, “The past is not dead. In fact, it’s not even past.” This certainly applies to the history of gaining and maintaining unequivocal U.S. support for Israel.

Today’s high-impact American groups such as AIPAC (which calls itself “America’s Pro-Israel Lobby”), Christians United for Israel (“the largest pro-Israel organization in the U.S., with more than a million members,” according to the Jerusalem Post) and similar outfits have built on 65 years of broad and successful Israel advocacy in the United States.

Baked into the foundation of their work was the premise of mutuality and compatibility of Israeli and American interests. Until the end of the Cold War, routine spin portrayed aid to Israel as a way to stymie Soviet power in the region. Especially since 9/11, U.S. support for Israel has been equated with support for a precious bulwark against terrorism.

Ever since the successful 1947 campaign to press for UN General Assembly approval of Palestine partition, Israel’s leaders have closely coordinated with American Jewish organizations. Israeli government representatives in the United States regularly meet with top officers of American Jewish groups to convey what Israel wants and to identify the key U.S. officials who handle relevant issues. Those meetings have included discussions about images of Israel to promote for the American public, with phrases familiar to us, such as “making the desert bloom” and “outpost of democracy.”

As any member of Congress is well aware, campaign donations and media messaging continue to nurture public officials cooperative and sympathetic to Israel. For the rare officeholders and office seekers who stand out as uncooperative and insufficiently sympathetic, a formulaic remedy has been applied: withholding campaign donations, backing opponents and launching of media vilification. Those political correctives have proved effective — along the way, serving as cautionary tales for politicians who might be tempted to step too far out of line.

The mainstream American Jewish Committee decided in 1953 that for its pro-Israel advocacy, “To the utmost extent, non-Jewish and non-sectarian organizations should be used as spokesmen.” Such a strategic approach has borne fruit for the overall Israel advocacy project in the USA. It is time-tested and mature; broadly distributing messages through organizations of most political flavors; and adept at touching almost all sizable media.

This year, Israeli leaders have intensified their lurid casting of Iran as the next genocidal Third Reich, and Israel as the protector absent for Jews during the Holocaust. For some, the theme is emotionally powerful. But it must not be allowed to prevent a diplomatic resolution of the nuclear dispute with Iran.

From now till next summer, the struggle over talks with Iran will be fierce and fateful. All signs point to determined efforts by Israel — and its many allies in the United States — to wreck prospects for a peaceful solution.
